I never denied that there are experts in the game. The point here is perception versus reality in the context of what is reliable, given that the OP recommends that these elements become primary consultants for design choices for the game.That's what make people see someone as an expert, ED has been out for little over 4 years now, there are people who play it as if it was their second job and stack up as many hours as a good RL pilot.
There is no "expert" test for anything, you get to be an expert by simply being good at something.
Under that logic, even FD aren't experts in ED... and it shows.
If Frontier were to consult on that basis, there is no method of verification, and so perceived expertise is not a reliable gauge to determine the weight of contribution. That's aside from the transient nature of players as perhaps a more serious issue in terms of reliability.
